As Lionel Fourquaux said, it should be possible: just replace /MT by
/MD in the source file config/Makefile.nt and rebuild the whole system.
However, there is an issue with the Unix library, which uses an
undocumented C library function _dosmaperr() to convert from Win32
error codes to Unix-style error codes. This function is not exported
by the DLL version of the MSVC C library. Yes, it's a stupid mistake
of mine to rely on this function, and I should have reimplemented my
own.
What Lionel suggests is to get the source code for _dosmaperr() from
the MSVC C library sources, recompile it and add it to your code.
Ponder legal issues before doing this, though.

The MSVC CD should contain (or used to contain) a ZIP file with the
sources for the C run-time library (look for files or directories
called CRT or something like it). The source code for _dosmaperr() is
somewhere in there.
Good luck,
